Question 80

The cost price of 5 kg of wheat and 10 kg of sugar was at Rs. 70 and Rs. 80 per kg respectively. On selling, he gained 10% on wheat and 20% on sugar. What was the total sale price?

Solution

C.P of 5 kg wheat = $$5\times\ 70=350$$

S.P of 5 kg of wheat at 10% profit = $$350\times\ \frac{110}{100}=385$$

C.P of 10 kg of lentils = $$10\times\ 80=800$$

S.P of 10 kg of lentils at 20% profit = $$800\times\ \frac{120}{100}=960$$

Total S.P = 385 + 960 = Rs 1345.
